Title: Semiconductor testing system
Inventor: SAWADA KEIICHI
IPC: H04L1/14
Filed: 1990-09-04
Abstract: PURPOSE:To discover an open place on each transfer line in a short time, easily and accurately by a method wherein a semiconductor testing system is provided with an open place detector, which specifies the open place in each transfer line on the basis of the state of the waveform of each reflected signal that a signal inputted in each transfer line is reflected at the open place in each transfer line and is returned. CONSTITUTION:An open place detector 12 is provided with a waveform generating register 14, a variable voltage generating circuit 16 for waveform generation use, a waveform detecting register 18 and a waveform voltage comparison circuit 20 for waveform detection use. The circuit 20 compares the waveforms of reflected signals returned in an inspection of verification of an actual connection with the waveform of reference data being stored in the register 18. In case the waveforms of the reflected signals coincide with the normal waveform signal, the normal waveform signal is sent out to a control device 2 and in case the normal waveform signal coincides with either of open waveform signals, an open place indicating signal is sent out to the device 2 and when the indicating signal is different from any one of the above signals, data on the waveforms of the reflected signals is sent out to the device 2 along with an abnormal signal.

Title: Automatic hot water filling up apparatus and automatic hot water filling up control device
Inventor: NOGUCHI YUKINOBU
IPC: F24H1/00
Filed: 1995-08-21
Abstract: PROBLEM TO BE SOLVED: To provide an automatic hot water filling up apparatus which prevents hot water from overflowing from a bathtub during automatic hot water filling up operation and an automatic hot water filling up control device for this apparatus. SOLUTION: A reference water level, which is slightly higher than the elevation of a circulation opening of an additional heating circulation passage to be connected to a bathtub is preliminarily stored in a water level memory 28 during operation in a memory mode. When hot water is being filled up in an execution mode based on the control of an operation control unit 27, the flow of hot water in the bathtub is detected with an additional heating flowing water switch 16 when a circulation pump 18 is driven. After the flow of hot water is detected, a water level comparison determination unit 29 determines whether or not the detected water level in the bathtub hot water to be detected with a pressure sensor 13 exceeds the reference water level.  When the detected water level exceeds the reference level, the amount of injection hot water from this detected water level to a setting water level is determined by an injected hot water volume arithmetic operation unit 26, thereby injecting hot water. When the detected water level is less than the reference water level, the amount of injected hot water from the reference water level up to the setting water level is injected, thereby filling hot water.

Filed: 1993-09-21
Abstract: PURPOSE:To manufacture a high-performance element with an improved yield by reducing the generation probability of element manufacturing failure caused by the surface defect, overetching etc., of an oxidation-prevention layer. CONSTITUTION:Since an etching-prevention layer 106 with a larger prohibition band width than that of an active layer 104 and a lower mixed crystal ratio than Al of a second clad layer 105 is provided between the second clad layer 105 and the oxidation-prevention layer 107, the etching-prevention layer 106 with a lower Al mixed crystal ratio is exposed even if the oxidation-prevention layer 107 is eliminated due to surface defect, overetching etc., partially in a process for eliminating the second clad layer 105 by selectively etching a layer with a higher mixed crystal ratio of Al for forming a stripe-shaped groove part 112. Etching stops at this layer, thus preventing etching liquid from reaching an etching stop layer 108 for etching. Also, even if the etching-prevention layer 10 is exposed, oxidation can be suppressed relatively, thus easily performing a second film growth and reducing poor influence to element characteristics and life.

Title: Manufacture of conductivity-modulation mosfet
Inventor: SEKI YASUKAZU
IPC: H01L29/739
Filed: 1991-09-17
Abstract: PURPOSE:To prevent the decrease in avalanche voltage due to parasitic transistors at the surface layer of a semiconductor substrate by preventing impurity from entering the edges of the substrate when a channel region of one conductivity is formed by doping. CONSTITUTION:When impurity is introduced in a wafer masked by a polycrystalline silicon gate to form a p-type region 4, surfaces near peripheral edges 9 are masked so that the peripheral region may not be doped. If many IGBT chips are formed on one wafer, a mask is applied to shield the borders between chips from impurity. Such a mask is easily prepared by applying resist over the wafer surface and patterning it by photoetching. The diode formed of the p-region 4 and an n<-> region 3 in this manner undergoes no deterioration of breakdown voltage due to parasitic transistors and has strong avalanche resistance.
